19828 Federal Register / Vol. 72, No. 76 / Friday, April 20, 2007 / Proposed Rules 

For the reasons discussed above, I 

certify that the proposed regulation: 

1. Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866; 

2. Is not a ‘‘significant rule’’ under the 

DOT Regulatory Policies and Procedures 

(44 FR 11034, February 26, 1979); and 

3. Will not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this proposed AD and placed it in the 

AD docket. See the ADDRESSES section 

for a location to examine the regulatory 

evaluation. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Safety. 

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part 

39 as follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

2. The Federal Aviation 

Administration (FAA) amends § 39.13 

by adding the following new 

airworthiness directive (AD): 

Airbus: Docket No. FAA–2007–27925; 

Directorate Identifier 2006–NM–183–AD. 

Comments Due Date 

(a) The FAA must receive comments on 

this AD action by May 21, 2007. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to all Airbus Model 

A310 series airplanes, certificated in any 

category. 

Note 1: This AD requires revisions to 

certain operator maintenance documents to 

include new inspections and critical design 

configuration control limitations (CDCCLs). 

Compliance with the operator maintenance 

documents is required by 14 CFR 91.403(c). 

For airplanes that have been previously 

modified, altered, or repaired in the areas 

addressed by these inspections and CDCCLs, 

the operator may not be able to accomplish 

the inspections and CDCCLs described in the 

revisions. In this situation, to comply with 14 

CFR 91.403(c), the operator must request 

approval for an alternative method of 

compliance according to paragraph (j) of this 

AD. The request should include a description 

of changes to the required inspections and 

CDCCLs that will preserve the critical 

ignition source prevention feature of the 

affected fuel system. 

Unsafe Condition 

(d) This AD results from fuel system 

reviews conducted by the manufacturer. We 

are issuing this AD to prevent the potential 

of ignition sources inside fuel tanks, which, 

in combination with flammable fuel vapors 

caused by latent failures, alterations, repairs, 

or maintenance actions, could result in fuel 

tank explosions and consequent loss of the 

airplane. 

Compliance 

(e) You are responsible for having the 

actions required by this AD performed within 

the compliance times specified, unless the 

actions have already been done. 

Revise Airworthiness Limitations Section 

(ALS) to Incorporate Fuel Maintenance and 

Inspection Tasks 

(f) Within 3 months after the effective date 

of this AD, revise the ALS of the Instructions 

for Continued Airworthiness to incorporate 

Airbus A310 ALS Part 5—Fuel Airworthiness 

Limitations, dated May 31, 2006, as defined 

in Airbus A310 Fuel Airworthiness 

Limitations, Document 95A.1930/05, Issue 1, 

dated December 19, 2005 (approved by the 

European Aviation Safety Agency (EASA) on 

March 13, 2006), Section 1, ‘‘Maintenance/ 

Inspection Tasks.’’ For all tasks identified in 

Section 1 of Document 95A.1930/05, the 

initial compliance times start from the later 

of the times specified in paragraphs (f)(1) and 

(f)(2) of this AD, and the repetitive 

inspections must be accomplished at the 

intervals specified in Section 1 of Document 

95A.1930/05, except as provided by 

paragraph (g) of this AD. 

(1) The effective date of this AD. 

(2) The date of issuance of the original 

French standard airworthiness certificate or 

the date of issuance of the original French 

export certificate of airworthiness. 

Initial Compliance Time for Task 28–18–00–

03–1 

(g) For Task 28–18–00–03–1, ‘‘Operational 

check of lo-level/underfull/calibration 

sensors,’’ identified in Section 1, 

‘‘Maintenance/Inspection Tasks,’’ of Airbus 

A310 Fuel Airworthiness Limitations, 

Document 95A.1930/05, Issue 1, dated 

December 19, 2005: The initial compliance 

time is the later of the times specified in 

paragraphs (g)(1) and (g)(2) of this AD. 

Thereafter, Task 28–18–00–03–1 must be 

accomplished at the repetitive interval 

specified in Section 1 of Document 

95A.1930/05. 

(1) Prior to the accumulation of 40,000 

total flight hours. 

(2) Within 72 months or 20,000 flight hours 

after the effective date of this AD, whichever 

occurs first. 

Revise ALS to Incorporate CDCCLs 

(h) Within 12 months after the effective 

date of this AD, revise the ALS of the 

Instructions for Continued Airworthiness to 

incorporate Airbus A310 ALS Part 5—Fuel 

Airworthiness Limitations, dated May 31, 

2006, as defined in Airbus A310 Fuel 

Airworthiness Limitations, Document 

95A.1930/05, Issue 1, dated December 19, 

2005 (approved by the EASA on March 13, 

2006), Section 2, ‘‘Critical Design 

Configuration Control Limitations.’’

No Alternative Inspections, Inspection 

Intervals, or CDCCLs 

(i) Except as provided by paragraph (j) of 

this AD: After accomplishing the actions 

specified in paragraphs (f) and (h) of this AD, 

no alternative inspections, inspection 

intervals, or CDCCLs may be used. 

Alternative Methods of Compliance 

(AMOCs) 

(j)(1) The Manager, International Branch, 

ANM–116, Transport Airplane Directorate, 

FAA, has the authority to approve AMOCs 

for this AD, if requested in accordance with 

the procedures found in 14 CFR 39.19.

this rule and if that provision may be 

severed from the remainder of the rule, 

we may adopt as final those provisions 

of the rule that are not the subject of an 

adverse comment. 

We do not plan to open a second 

comment period, so anyone interested 

in commenting should do so at this 

time. If we do not receive adverse 

comments, no further activity is 

planned. For further information, please

ENVIRONMENTAL PROTECTION

40 CFR Part 52 

[EPA–R05–OAR–2006–0609; FRL–8302–7] 

Approval and Promulgation of Air 

Quality Implementation Plans; 

Wisconsin; NSR Reform Regulations, 

Rule AM–06–04 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Proposed rule. 

SUMMARY: EPA is proposing to approve 

certain revisions to Wisconsin’s 

prevention of significant deterioration 

(PSD) and non-attainment new source 

review (NSR) construction permit 

programs submitted on May 25, 2006. 

On December 31, 2002, EPA published 

revisions to the federal PSD and nonattainment NSR regulations. These 

revisions are commonly referred to as 

‘‘NSR Reform’’ regulations, which 

became effective on March 3, 2003. 

These regulatory revisions include 

provisions for determining baseline 

actual emissions, provisions for 

promulgating actual-to-future actual 

methodology, provisions for 

establishing Plantwide Applicability 

Limits (PALs), provisions for using the 

Clean Unit test, and, provisions for 

using Pollution Control Projects (PCP). 

On June 24, 2005, the United States 

Court of Appeals for the District of 

Columbia Circuit (DC Circuit Court) 

issued its ruling on challenges to the 

December 2002 NSR reform revisions. 

Although the Court upheld most of 

EPA’s rules, it vacated both the Clean 

Unit and the PCP provisions. In 

addition, the Court remanded to EPA 

the provision that requires 

recordkeeping and reporting for sources 

that elect to use the actual-to-projected 

actual emission test only where there is 

a reasonable possibility that a project 

may result in a significant net emissions 

increase. EPA is currently working on 

promulgating a rule that will clarify the 

reasonable possibility provision. EPA’s 

final decision with regard to the remand 

may require Wisconsin to revise this 

portion of its rules to be consistent with 

EPA’s definition of reasonable 

possibility. The Wisconsin Department 

of Natural Resources (WDNR) is seeking 

approval of rule AM–06–04 to 

implement the NSR Reform provisions 

that have not been vacated by the June 

24, 2005, DC Circuit Court decision. 

This action affects major stationary 

sources in Wisconsin that are subject to 

or potentially subject to the PSD, and 

non-attainment NSR construction 

permit programs. 

DATES: Comments must be received on 

or before May 21, 2007.
